A navigation system for guiding a moving object from a current position to a destination includes a setting device that sets the current position and the destination, a sensor that detects movement of the moving object, a computing device that calculates move distance that the moving object has moved from the current position based on data outputted from the detecting sensor, and that determines a position of the moving object by shifting the calculated move distance from the current position on path data between the current position and the destination, which has been obtained by a path planning. The navigation system further includes a display device for displaying path guidance information depending on the determined position of the moving object.

What is claimed is: 1. A navigation system for guiding a moving object from a current position to a destination comprising: a setting device that sets the current position and the destination, using map information; a sensor that detects movement of the moving object; a computing device that calculates a move distance, without regard to a direction of movement, that the moving object has moved from the current position based on data outputted from the sensor, the computing device determining a position of the moving object by shifting the current position by the calculated move distance, along a designated path defined by designated path data between the current position and the destination, which designated path data have been determined by a path planning; and a display device for displaying path guidance information depending on the determined position of the moving object; wherein, said display device displays said designated path as nodes and links in a linear map arrangement, as path guidance information; and when said moving object approaches a particular intersection or corner, said display device further displays a two-dimensional partial map which indicates that particular intersection or corner by using map information, to prompt the moving object to change its orientation. 2. The navigation system according to claim 1, wherein: the computing device compares a distance between the current position and a predetermined position with the calculated move distance on the designated path data; and the display device displays path guidance information about the predetermined position based on results of the comparison obtained by the computing device. 3. The navigation system according to claim 2, wherein the predetermined position is a position at which there occurs a change of an orientation of the designated path along which the moving object moves. 4. The navigation system according to claim 2, wherein the predetermined position is a position at which path conditions change in the designated path data. 5. The navigation system according to claim 1 further comprising a position detecting device for detecting whether or not the moving object has reached a predetermined position on the designated path data, wherein the calculated move distance is corrected based on outputted data from the detecting device. 6. The navigation system according to claim 5, wherein the detecting device uses any one of RFID, radio beacons, WLAN or GPS. 7. A method for path guidance for guiding a moving object from a current position to a destination comprising steps of: setting the current position and the destination; calculating a move distance, without regard to a direction of movement, that the moving object has moved from the current position; determining a position of the moving object by shifting the current position by the calculated move distance along a designated path defined by designated path data between the current position and the destination, which designated path data have been determined by a path planning; and displaying path guidance information depending on the determined position of the moving object; wherein, said displaying step comprises, displaying said designated path as nodes and links in a linear map arrangement, as path guidance information; and when said moving object approaches a particular intersection or corner, displaying a two-dimensional partial map which indicates that particular intersection or corner, to prompt the moving object to change its orientation.
